3.7  Costs
                  To get an accurate impression of the macro-economic effects of the PowerCem technology, a
                  distinction is made between the direct and the indirect costs. The direct costs consist of the
                  required measures to get the infrastructure operational.
                  The indirect costs are the costs as result of a non-working infrastructure and are not always
                  expressed in exact values.

                  The costs for the different constructions and measures are partly based on actual verified
                  prices. Since not all the verified prices were available, the rest of the costs are assumed based
                  on expert judgment.

                  The costs used for the study are extended by the following topics:
                      -   Unit prices.
                      -   Traditional constructions.
                      -   RoadCem constructions.
                      -   Measures.
                      -   Indirect costs.

                  3.7.1  Unit prices
                  In this sub-paragraph all the unit prices are given which are further calculated. The unit prices
                  are divided in the following topics:
                      -   Material costs.
                      -   Construction costs.

                  Materials
                  All the materials used for the different constructions are summarized in table 3.12.
